You are moving into an apartment and take the elevator to the 6th floor. Suppose your weight is 690 N and that of your belongings is 940 N. (a) Determine the work done by the elevator in lifting you and your belongings up to the 6th floor (15.2 m) at a constant velocity. (b) How much work does the elevator do on you alone (without belongings) on the downward trip, which is also made at a constant velocity?A person pushes a 16.0kg shopping cart at a constant velocity for a distance of 22.0 m. She pushes it in the direction 30.0\" below the horizontal. A 48.0-N frictional force opposes the motion of the cart. (3} Draw the free-body diagram showing the forces that act on the cart. {b} What is the magnitude of the force that the shopper exerts? Determine the work clone by {c} the pushing force, {d} the frictional force, and (oi the gravitational force
